HDS03.2-W075N-HT12-01-FW
The HDS03.2-W075N-HT12-01-FW is a drive controller from Bosch Rexroth Indramat. It occupies one slot in the power rack and controls a single three-phase servo axis within a multi-axis system. In industrial automation, it converts setpoint data from a higher-level control network into precise motor current, supporting closed-loop regulation for positioning, velocity, and torque tasks on assembly robots, gantries, and machine tools. It is suited for applications that require repeatable motion and fast response during acceleration and reversal.
Communication with the unit is handled through the SERCOS fiber-optic interface, which provides deterministic timing for motion commands and feedback. As part of the DIAX04 platform, it uses the same general configuration structure as related modules in the rack. Deterministic communication helps coordinate this axis with other interpolated drives when multiple motions must stay synchronized. Thermal management is provided by a built-in air blower mounted behind the heat sink, and the power section delivers a continuous current of 75 A for medium-size permanent-magnet or induction servo motors. The module slides into the power rack and draws energy from the shared DC bus, so it operates as a plug-in axis controller rather than a standalone drive package.
Within the HDS Drive Controllers series, this unit is identified as Line 03. The controller is Version 2. The parameter group for the command communication interface includes adjustable telegram lengths, sync periods, and status word formats, allowing data exchange to match controller requirements without changing the motion program. Adjustable sync periods let the drive follow the update cycle used by the control system. Different telegram lengths also let the application balance transferred data against cycle time.
